How do I find the format of a file whose extension is incorrect ?
Very often fall on files whose format is not the right. For example, a movie. avi renamed. jpg to hide, or a file whose extension has been removed.
Find the extension manually to know which program to open the file is something simple, but may take time if it is not a known extension… And yet he must have the correct program to open the file at the end !
So here, if you do not know the extension of a file, TrIDNET let the searching for you. You open the software, load files “definition” (software to be used to compare the different file extensions possible), indicate which file scanner, and you are its original format.
I used the example file that we all had once… The file named “File”, no extension (it's actually a simple image I renamed).

In two clicks he managed to find myself starting the extension, in telling me the same number of “definitions” he scanned before finding.
This is a program that would have been used a couple of times if I had known earlier, and who is not ready to leave my software library !
Thank you to Blumenka to find.
Download TrIDNet !
Download the definitions of the software


So basically with ca : Saiki finished films disguised as. jpg :/
The extensions will in secret
Formidable, hard 1 once a year but essential.
The worst since Vista, is that the extensions associated with applications are automatically hidden, y compris sous Windows Explorer… Good luck to see if a file VLC is a bin, avi, mpeg, etc..
Here is an excellent solution.
No you do not have to hide.
Tools, folder options, and you are looking for “Hide extensions whose type is known”, something like that.
